Helminths of Foxes and Coyotes in Florida
stomach; a second whale contained three specimens encysted in the fundic stomach and duodenum. The nematode, Anisakis typica, constitutes another new record for this host, though not unexpected because this parasite is common in cetaceans from warm and tropical waters (Davey, 1971, J. Helminthol. 45:51-72). Specimens of A. typica were found in the foreand fundic stomach in all three whales. Int...
متن کاملDispersal characteristics of swift foxes
From 1997 to 2001, we monitored movements of 109 adult and 114 juvenile swift foxes, Vulpes velox (Say, 1823), at study sites in Colorado, New Mexico, and Texas to determine patterns of dispersal. Significantly more male (93%) than female (58%) juveniles dispersed, and both sexes had similar bimodal dispersal patterns with peaks in September–October and January–February. Adult dispersal occurre...
متن کاملFood habits and space use of gray foxes in relation to sympatric coyotes and bobcats
To investigate interspecific relationships between gray foxes (Urocyon cinereoargenteus) and sympatric coyotes (Canis latrans) and bobcats (Lynx rufus), we quantified occurrence of food items in carnivore scats and used relative abundances of scats on transects to assess space use. Dietary-overlap indices between the two canid species were high during summer and fall (x = 0.89) when fruits were...
متن کاملWolves-coyotes-foxes: a cascade among carnivores.
Due to the widespread eradication of large canids and felids, top predators in many terrestrial ecosystems are now medium-sized carnivores such as coyotes. Coyotes have been shown to increase songbird and rodent abundance and diversity by suppressing populations of small carnivores such as domestic cats and foxes. The restoration of gray wolves to many parts of North America, however, could alt...
متن کاملCoyotes, Red Foxes, and the Prevalence of Lyme Disease
Lyme disease is the most prevalent vector-borne disease in north temperate areas worldwide, with the majority of cases reported in the northeastern United States. The transmission cycle involves ticks, deer, small mammalian hosts such as mice, and numerous other species. Levi et al. (2012) suggested that Canis latrans (Coyote) abundance and Vulpes vulpes (Red Fox) scarcity are strong predictors...
